NGR
The compact repelletizing solution for any type of film
A chopper-feeder-extruder combination with a space-saving design, an energy-efficient drive and simple, intuitive operation. The E:GRAN is the re-processing technology for thermoplastic film edge trims and roll scraps — clean enough to be installed directly inside a production hall.

Plastic film and film edge trim are chopped directly in the extruder feed section. The conically shaped conveying area of the screw compresses the material as it enters the extruder.
In the extruder, the material is brought to a uniform melt temperature and subsequently pelletized.
The feed section (where the material is chopped), conveying area and the extruder all lie along a single shaft. The resulting design requires only one energy-efficient drive.
All the components are positioned in close proximity to prevent oxidation of the material and to make optimal use of heat from the chopping process.
All models in the E:GRAN series feature this patented chopper-feeder-extruder combination.
An innovative chopper/feeder design prepares film effectively and adjusts extruder speed automatically to fluctuating edge-trim volumes.
Runs so cleanly it can be installed directly in production halls, right next to the film line.
Chopper, feeder and extruder work in a single process — no intermediate steps, switched on and off with one push button.
All edge trim and roll scrap is fed straight back into production for a precise, consistent output.
Robust design engineered for continuous, energy-efficient running in a compact footprint.
| Model | Extruder screw Ø (mm) | Feed screw Ø (mm) | Max output (kg/h) | Max output (lbs/h) |
|---|---|---|---|---|
| E:GRAN 50-12 | 50 | 120 | 50 | 110 |
| E:GRAN 75-16 | 75 | 160 | 120 | 270 |
The air separator is used in the production process to continuously recycle film edge trim, which is fed pneumatically into the machine. With "inline operation," further material handling is unnecessary, and the NGR recycling machine is now fully automated.
With variable feed speed, roll scrap is treated in a process-controlled manner. The virtually unmanned machine is fed continuously. The roll feeder can be operated at the same time with other types of feeding (e.g. conveyor belt).
Designed for light printing and low humidity. The vacuum degassing system includes a vacuum pump and is connected to two venting ports on the extruder.
Each venting combination can be equipped with a closed water circuit. The fresh water consumption at the vacuum pump is thereby reduced significantly.
For thermoplastics with a higher viscosity. The melt exits through the wear-resistant die plate, and is knocked off by the pelletizer blades. The pellets cooled in the water ring are flushed out, dried in the centrifuge and discharged. By adjusting the blade pressure, pelletizer blades provide a long service life; replacement is quick and easy.
Specially designed for inline applications where water is not used. The melt exits through the wear-resistant die plate, and is knocked off by the pelletizer blades. The pellets are carried away in the air stream and cooled.
For clean, in-house production waste. Using the manual lever, two screens can be swung out alternately to allow for cleaning of the melt stream. The process is discontinuous, because the machine has to be switched off to change the screen.
The throughput scale is integrated in the machine control system and displays the current production output in kg/h (lbs/hr). The data can be logged in a BDE system.
Solid engineering, high-quality materials and precise execution ensure a long service life for equipment.
Maintenance-friendly access to moveable parts allows you to quickly change material, efficiently disassemble and assemble wear and tear parts, and minimizes downtime.
